Frequently Asked Questions

Every leak is different, so we offer two options: an hourly rate (minimum one-hour charge, then 30-minute intervals) or a fixed-price investigation if you want certainty before work begins, which also suits insurance claims.

Before any work starts, we'll agree the best option with you so you know exactly how you'll be charged. See our full guide to leak detection costs.

Common signs: a damp patch on a wall, ceiling or floor that won't dry out, a musty smell that won't go away, your water bill jumping without explanation, low water pressure, or the sound of running water when nothing's turned on. If you're seeing any of these — even just one — it's worth getting checked before it gets worse (and more expensive).

If it's a genuine emergency, call us — we aim to be on-site within a few hours, 24/7. For anything non-urgent, we can usually get you booked in within a week.

Our approach is to locate leaks using non-invasive detection methods wherever possible, helping to minimise disruption to your property.

We use specialist equipment including thermal imaging, moisture mapping, tracer gas, and other diagnostic methods to identify the source of leaks without unnecessary damage.

If access is required during an investigation, we will always discuss this with you beforehand and explain the reason why it is necessary.

Yes, we provide leak repair services alongside our detection investigations.

Once the source of the leak has been identified, we can carry out suitable repairs where possible. If a repair falls outside the work we handle directly, we'll be upfront about this and point you towards a trusted specialist rather than taking on work that isn't the right fit.

Our priority is always to provide the correct solution for your property.

The duration of an investigation depends on several factors, including the type of leak, the property's construction, accessibility, and the diagnostic methods required.

Some investigations may be straightforward, while others require a more detailed assessment to accurately identify the source of the issue.

We take the time needed to carry out a thorough investigation and provide you with clear findings and recommendations.

In the vast majority of jobs we find it. On the rare occasion we can't pinpoint it, we'll tell you plainly and point you toward next steps, including a trusted contractor if it's outside our scope. You're paying for our time, expertise and equipment on the day either way, but that's rarely the outcome. More on how charging works if we can't find it.

Yes, we assist customers with insurance-related leak investigations by providing detailed findings and professional reports where required.

Our reports can include details of the investigation, testing carried out, results, and recommendations to help support your insurance claim.

Please note that insurance policies and claim requirements vary, so we recommend checking with your insurer before arranging any work.

Fixed-price investigation quotes can also be provided where required for insurance purposes.
